pulasan

Scientific name: Nephelium ramboutan-ake
Family: Sapindaceae (same family as rambutan)

Description: Tree reaching 9-14 (exceptionally 40) m with a short trunk and a wide, rounded crown. Dioecious. Leaves alternate, compound, with 2-5 pairs of glossy leaflets. Flowers small, greenish, in branched axillary or terminal panicles. Fruit round to ovoid, about 5-7.5 cm in length, with a bumpy red, purple or yellow peel. The pulp is white or yellowish, translucent, juicy, sweet and aromatic and with a single seed the size and shape of an almond.
Habitat: Primary Mixed Dipterocarp Forest or sometimes Secondary Forest, on flat lands, slopes and riverbanks. From sea level to about 1,950 m elevation.
Soil: Clay, loam or sometimes rocky soil
Distribution: Native to Southeast Asia (Malaysia, Indonesia and the Philippines).

Culture: Grows well where abundant moisture is available year round, although it does tolerate brief periods of drought. Best growth is achieved in fertile, well drained soils. Regular fertilization will also improve growth and fruiting.
The most important related species is the Rambutan (Nephelium lappaceum), but there are at least 30 other wild species of Nephelium with edible fruits.
